Application filed February 20, 1925. Serial No. 10,457.

' To all whom t may concern:

Zylonite (Celluloid),

f appearance: forming an improvement: over anything previouslyknownin this respect. Affurther object-of thepresentfinvention i isthe provision oan improved :construction'linwhich the temples. Aandv fronts shall be sounited asfto accomplishthe results as above indicatedk with I a: y reduced 'pupilla-ry width of frames of the character referredto, rendering vthe y mounting more satisfactory both; from #considerations otappearance and the avoidancey of undesirablelateral projections, .and furthermore in which the'` tront adjacentthetemple shall/bev of smooth and unbrokenform, and infwhichthefhi-ngestor the frame shall be disposed in inconspic'uous position concealedl `when the mounting -is viewedfrom the front and. unsightlyf lateral projections, allordingl hinged connections or attachments, shallbe eliminated. j

It has been proposedlto accomplish :the above obj ects byv having rearwardly `curved endpiece portions to `which the' temples are hinged, the temples abuttingagainst the ends of the projections which,` by reason-of the curvature ofthe'projections, tace rearwardly. This, however, involves thelabor and trouble incident to produce lthe curved projections as projections andmetal-lic reinforcement ot these curved projectingV end piece-portions is required to vprevent the accidental straightening thereof.

According to vthe present inventionf-it -is proposed to accomplish `all of the lresults as indicated by the useo'f"straightrather-than rearwardly curved end-piece projections, the temple abutting against the side of the projection rather than the end thereof.

A further object ofthe invention is -to :distinguished Afrom straight provide a mounting of the desirable appearance as indicated but in which the parts are readily repaired or replaced upon injury or breakage ofthem.v

Other and ancillary objects of the .invention will appear hereinafter. n'

In the accompanying drawings which illustrate thein'vention- Fig. l .is a perspective View of one side of a spectaclezframe showing the manner of attachment of a templeto the :t1-ont, sulficientV of the frame 'being shown to. illustrate the application of the'invention thereto but the -greater portion of the AJframe being broken away, it being understood that'the front consists of the usual'lens Aframes or rims connected by the nose piecel-orfbridge and that'the'otlier temple is secured yto the other side of the frame in the same manner as is illustrated in-this ligure;

Fig. 2 isa top-plan view of the temple and'frontconnection'as shown in Fig. 1,-the greater part of? the front and the one temple shown beingvbroken away; l

Fig. 3 is a sectionFon'the-line I3--3 of Fig. 2;.1and

Fig. is a section on-thelinc 4L-4c of Fig. .3.

Referring'to the drawingsfthe front I ot composition as above referredto'has integrally formed with'it the temple securing projecting end-piece 2. -The-temple 3 of similar vmaterial'is secured tothe frame by means of a vmetal hinge, the two members vof Vwhich are respectively-#secured to the temple '3 and the projection 2. The hinge-member secured tothe temple comprisesa flat plate tinteg-rally connected with the barrelsv 5. AThe plate i is inlaid upon the inside of the temple 3 so that Ytheir surfaces are substantially ilush-v and a Lrecess 6 is tormed inthe temple to accommodate a part of the hinged barrel, the hinged barrelslalso projecting beyond the end` 7 of the temple. This hinged member is secured to the temple by means `of a single circular rivet 8 which,y because ofthe'inlaying of the hinge rfirmly holds -th'e hinge member in properrrelation to the temple. A. shelllike pla-te 9 of material the same as the temple and integral therewith extends over the ends ot the hinge barrels both above and below so Aasto substantially remove the metallic portions Jfrom view.

The hinge member secured to the front Y comprises a flatnmetal platelO, inlaid into the projection 2 so that its surface is substantially flush with that oit' the inside surface of the projection, and also the barrels 11 integral with the plate lO. rIll-ere is formed in the projection 2 a recess l2 at the rear side of the projection receiving part of the hinged barrels, these barrels projecting somewhat to the rear of the projection as shown most clearly in Iiigs. 2 and Ll, the material 13 of the projection being outside the barrel of the hinge and adapted to abut against the end 7 ot the temple so that the exterior of the hinge is co-vered by the end of the temple and the projection 18 when the temple is in position on the wearer. rIhe outer corner of the projection may be rounded as shown at 16 to improve the appearance. I'Vhen not in use the temples can be 'folded inwardly in the usual manner to lie compactly against the spectacle :tr-ont. The hinge members are secured together by the usual pivot pin 14. In the case of the hinge member secured to the projection 2, this is also secured by a single rivet l5 and for reasons as stated this is sufficient to firmly secure the hinge to the frame front. The inlaid construction of the hinge, therefore, as shown with the single rivet tor each hinge member ena-bles the hinge plates to be shortened which is of particular importance in that it permits the projection 2 to be shortened whereby the compactness of the structure is enhanced.

In previous structures designed to attain the objects of the present invention it has been proposed to insert a tang forming a part of the hinge member endwise into the composition of the frame. In such cases damage or breakage of the hinge requires the whole frame to be thrown away because the hinge members cannot be sub stituted without a great deal of labor and probable destruction of the frame. VVit-h the present construction, however', a damaged hinge member can be removed by simply driving out a rivet and a new member put in place by inserting and securing the rivet in the usual manner.

Altogether a spectacle trame having the desired characteristics as above outlined is, by the present invention, attained in a peouliarly efficient, inexpensive and desirable manner.

lVhile the invention has been illustrated in what is considered its best application it may have other embodiments without de parting from its spirit and is not, therefore, limited to the structure shown in the drawing.
